Observable tests for the light-sail scenario of interstellar objects
Wen-Han Zhou, Shang-Fei Liu, Yun Zhang +1
We scrutinize the light sail scenario of the first interstellar object (ISO) 1I/2017 U1 (`Oumuamua) by making comparisons between physical models and observational constraints. The…
Orbital migration and circularization of tidal debris by Alfvén-wave drag: circumstellar debris and pollution around white dwarfs
Yun Zhang, Shang-Fei Liu, Douglas N. C. Lin
A significant fraction of white dwarfs (WDs) exhibit signs of ongoing accretion of refractory elements at rates -- kg s, among which, 37 WDs were detected to…
Tidal distortion and disruption of rubble-pile bodies revisited -- Soft-sphere discrete element analyses
Yun Zhang, Patrick Michel
During close approaches to planets or stars, the morphological and dynamical properties of rubble-pile small bodies can be modified, and some may catastrophically break up. This ph…
Tidal fragmentation as the origin of 1I/2017 U1 ('Oumuamua)
Yun Zhang, Douglas N. C. Lin
The first discovered interstellar object (ISO), `Oumuamua (1I/2017 U1) shows a dry and rocky surface, an unusually elongated short-to-long axis ratio , a low velo…
